I like and want to keep my factory 17" billett wheels. Since these are 8" wheels and the Mustang has limited clearance, want is the widest tire I can put on the factory rims? I would not want to mess up my speedo, any tire recommendations?
I went with the NITTO 255/50/17 on the rear of my 05 and left the front alone for now. It allowed me to keep the same tire dia. Try this link to chech sizes.
